I listened to a pair last week and I am a fussy pain in the butt looking for something that is all things to all men (Punchy Bass, Vocals, Open Soundstage, Sparkle and Life, for Multiple applpications etc).
Every pair I I have listened to had a box it couldn't really tick (unless I spend silly money I fear).
The HP100's pretty much ticked all the 'audio' boxes...
My only issue (and of course it's a personal one) was looks... I just think they look like a cheap budget brand and not like a £150 piece of mid-range audio!
But if you like the looks (and they are sleek and they are comfy too!), and their price is in your range, then I think you really need to have a listen...
